Back Pressure Regulator

CAD Model


Description: The BPR series back pressure regulator functions very much like a relief valve. It contains a normally closed valve element, and is typically placed at the end of the fluid line. The regulator will crack open when pressures upstream reaches the set pressure (adjustable), allowing excess pressure to vent through the outlet port. When pressures drop slightly below the set pressure, the regulator will close again.

Max Inlet Pressure Rating: The BPR can handle a maximum inlet pressure of 500 psi.
Cracking Pressure Range: Maximum cracking pressure range 0-400 psi. Piston style regulators contain coil springs, and are especially well suited for applications requiring higher outlet pressures (minimum 10 psi).
Approximate Weight: 72g in brass and stainless steel and 33g in aluminum. Weight will vary slightly, depending on configuration.
Porting: Eight different porting configurations are available. See images to the left for more information.  Except for porting type 2, all regulators use 10-32 ports.

Seals: Silicone seals are available for the BPR regulator, but they are not recommended.  Silicone may wear quicker as well as reduce performance.  If you require Silicone in your application, please contact us for further details.
